Microsoft has agreed to comply with the European Commission's recent anti-trust ruling and won't be appealing the decision. 

In addition, the software giant has complied with all of the issues raised in the anti-trust suit and has already been fined both in 2004 and 2006 for non-compliance.
In September, Microsoft lost its appeal to the European Commission judgement that it has abused its dominant market position and ordered to pay the imposed fine of almost half-a-billion Euros.
The Court of First Instance decided that the Commission had acted correctly in its original judgement. It did, however, annul one of the orders, that Microsoft set out a proposal to the Commission for establishing a "suitable mechanism" in monitoring compliance.
Instead, the Court ordered Microsoft to submit a proposal for the establishment of a mechanism which is to include a monitoring trustee with the power to have access, independently of the Commission, to Microsoft’s assistance, information, documents, premises and employees and to the source code of the relevant Microsoft products.
All other parts of the original judgement were upheld, including the fine of almost half-a-billion Euros.
The original judgement found that Microsoft infringed Article 82 EC and Article 54 of the Agreement on the European Economic Area (EEA) by twice abusing a dominant position, for operating systems and for Windows Media Player interoperability.
The first abusive conduct was Microsoft's refusal to supply its competitors with interoperability information and to authorise the use of that information for the purpose of developing and distributing products competing with Microsoft’s own products on the work group server operating systems market.
The second abusive conduct arose from the fact that Microsoft made the availability of the Windows client PC operating system conditional on the simultaneous acquisition of the Windows Media Player software.
In respect of the two abuses identified in the contested decision, a fine of E497 196 304.00 was imposed.
A number of other conditions were set, including the cessation of abusive practices, opening of its operating systems to competitors, and continual updating of interoperability information.
